I recently bought a copy of a book called Orchestrion and Pneumatics Builder's
Guide ( or something to that effect ) . In it are some plans showing how to
build a sophisticated, custom vacuum regulator for a build-up. The problem
is, I cant figure out the blueprints, nor does it give a clue as to how the
parts are assembled. Has anyone else tried to decipher them, or actually built
one of them. Or, does anybody else have a copy of this book?
